Whom did Koly think would have made her happier if they had lived?

Koly's belief that Hari would have made her happier if he had lived reflects her emotional connection to him and the dreams they had for their future together. Throughout the story, Koly envisions a life with Hari filled with love, companionship, and shared aspirations. Their relationship symbolizes hope and the possibility of a brighter future, contrasting with her experiences following his death, which bring her sadness and despair.

While her parents and Sassur are important figures in her life and influence her circumstances, Koly primarily associates her happiness with the love and potential she saw in her relationship with Hari. Sass, being a character that embodies certain qualities, also plays a role in Koly's journey, but it is Hari who truly represents the possibility of a fulfilling life and emotional fulfillment for Koly. Thus, it is Hari's absence that she feels most acutely and believes would have altered her happiness significantly.
